3 Claims. (01. 123-41.31)

This invention relates to an improved cooling means for stationaryengines.

An object of this invention is to provide an improved cooling means forstationary engines connected to irrigation well pumps wherein the waterwhich is pumped by the engine will provide a cooling medium for thewater in the engine cooling system.

Another object of this invention is to provide an improved coolingjacket which is interposed in the cooling system of the engine and isdisposed about the discharge pipe of the pump which is driven by theengine, so that the cool water discharged from the pump will cool thejacket and maintain the water in the latter cool.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claims.

In the drawing,

Figure 1 is a detail side elevation of an irrigation pump and engineconnected therewith having a cooling system constructed according to anembodiment of this invention, connected with the engine and the pump,

Figure 2 is a detail end elevation of the pump and engine,

Figure 3 is a sectional view taken on the line 33 of Figure 2,

Figure 4-. is a sectional view taken on the line 4-4 of Figure 3,

Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure3,

Figure 6 is a fragmentary sectional view taken on the line 66 of Figure5.

Referring to the drawing, the numeral ID designates generally a pumpwhich is connected with an irrigation well and which is operated bymeans of an engine II. The engine H is connected with the pump in bymeans of a shaft 12, and the engine H includes a cooling jacket I3having an outlet l4 and an inlet l5. The water which is discharged fromthe pump ID passes through a discharge pipe or water main l6 which isthreaded into a collar I1 and se cured by fastening means I8 to thedischarge side of the pump [0. A water reservoir 19 is disposed adjacentthe pump Ill being connected with the discharge nipple M of the enginejacket I3 by means of a tubular member 20. The reservoir I9 is supportedadjacent the discharge side of the pump ID by means of a pair ofvertically disposed angle members 21 which are secured to the collar ITby a pair of the -i.astening members 18. The water discharged into thereservoir l9 passes downwardly through an outlet 22 and enters a coolingjacket generally designated as 23.

The jacket 23 is interposed in the discharge pipe [6 and is formed of aninner wall 24 forming a bore alignable with the discharge opening of thepump I0 and may be formed of corrugated construction to provide anincreased cooling surface, and the jacket 23 also includes an outercylindrical wall 25. A pair of end walls 26 and 21 are secured to thewalls 24 and 25 and the outer wall 25 is provided with an intake nipple28 connected with the outlet 22 of the reservoir [9, by means offlexible hose 29. The outer wall 25 also has a lower outlet nipple 30with which a flexible hose 3| is connected, and the hose 3| is connectedwith an elongated pipe 32 which is connected to a relatively shortflexible hose 33. The hose 33 is connected to the intake nipple [5 ofthe engine jacket l3.

In the use and operation of this device, the jacket 23 is interposedbetween the ends of pipe l6, being welded or otherwise secured theretoso that'the water will flow through the jacket 23 within the confines ofthe inner wall 214, and the reservoir 19 is supported by the supportingbars 2| from the pump [0. The hot water from the engine will passthrough the outlet connection 20 into the top of the reservoir l9, andthe water will then pass downwardly through the hose 29 into the coolingjacket 23. The cool water passing through the inner wall 24 of thejacket 23 will cool the jacket and thereby cool the water entering thejacket 23 which is then returned to the engine ll through the returnconnections 31, 32 and 33. The cooling means hereinbefore described willtake the place of the radiator which is at present associated with theengine II and will eliminate the fan and other cooling means.

I do not mean to confine myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claims.

What I claim is:

1. In an internal combustion engine having a cooling jacket, a pumpoperated by said engine and connected to a water well for withdrawal ofwater therefrom, a discharge pipe extending from said pump, a reservoirconnected with the outlet side of said cooling jacket, a cooling memberinterposed in said discharge pipe having a surrounding water chamberdisposed radially of said discharge pipe, a connection between saidcooling member and said reservoir, and a connection between said coolingmember and the intake side of said jacket.

2. In an internal combustion engine having a cooling jacket, a pumpoperated by said engine and connected to a supply of water, a water mainextending from said pump for conducting a flow of water therefrom, areservoir connected with the outlet side of said cooling jacket, atubular cooling member having a circular passage encircling said watermain, a connection between said cooling member and said reservoir, and aconnection between said cooling member and the intake side of saidjacket. r

3. In an internal combustion engine having a cooling jacket, a pumpdisposed above, a water well connected to and operated by said enginefor pumping water from said well, a discharge means opening from saidpump, a reservoir connected said cooling means being formed as anextension of said discharge means with an inner wall engageable by thepumped water, a surrounding wall spaced from said inner wall havingspaced end walls extending inwardly therefrom to form a chamber disposedradially of said discharge means, a connection between said coolingmember and said reservoir, and a connection between said cooling memberand the intake side of said jacket.
